PUMP.

SPECIFICATION forming part of Letters Patent No. 303,339, dated Augustl2, 1884:.

Application filed November 14, 1883. (No model.)

10 all whom, it may concern.-

Be it known that I, Monnrs D. TEMPLE, of Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin Pumps; and I hereby declare the following to be a full, clear, andexact description thereof, which will enable others skilled in the artto which my invention re lates to make and use the same, reference beinghad to the accompanying` drawings, forming a part of this specification.

The object of my invention is, first, to construct a pump with a' bodyor barrel of wood, and with a bucket chamber or cylinder made of glass,hard rubber, metal, or enameled metal, and to unite said parts in such amanner that the value of the iinished structure cannot be in anywayinjured by the shrinking or by the swelling of the wooden part, and,second, to apply the same construction to iron pumps,

thereby making a better article and at the same time save much labor inthe construction ofthe same. This construction of apump with an internalcylinder attains three specitic ends, Viz: First, when the pump-barrelis made of wood, it provides a means ofiirmly securing the cylinderthereto in such amanner that the Wooden pump-barrel may shrink Withoutinjury to itself or the cylinder, and may swell without loosening` thecylinder from its position; second, the mechanism which secures suchinternal cylinder firmly in place also forms a seat for a checkwalve, iucorr nection with which any known form ol checkvalve may be used; third,this construction is equally applicable to iron pumps, whereby aporcelain or like cylinder for a bucketchamber may be fastened withinthe pump, being more desirable for the bucket to work in and moreeasilyrand cheaply made and applied than it is to bore out the roughcasting.

Metallic cylinders have been applied to Wooden pulnps hitherto either bydriving the cylinder into the bore of the pump-barrel or by driving thepump into the cylinder. In both cases the cylinders 'were held byfriotional contact and lateral pressure. When a metallic cylinder wasdriven into the bore of a pump, when the wood was not thoroughlyseasoned and the pump remained in store a length of time before beingused in a well, the wood was cracked, split, and ruined by shrinkingagainst the unyielding cylinder, or if the cylinder was made of glass,it was broken, being unable to resist thepressure of the shrinking wood.On th'e other hand, if the wooden barrel of a pump was thoroughly dry atthe time, a metallic cylinder was inserted, when put to use in a welland saturated with water, it swelled, enlarging the bore. The cylinderconsequently became loose, the water escaped, air was admitted, thesuction impaired or destroyed, and the, pump rendered useless.V

Agaiii, when wooden pumps were driven into metallic cylinders obversely,similar diiculties were encountered. By the shrinking of the wood thecylinders became loose and dropped ofi", by the swelling ot the wood thecylinders were cracked unless made very strong and heavy and much morecostly than in my construction, in which all said difficulties, arisingfrom dissimilar natural properties of the material used, are entirelyovercome.

In the drawings, Figure l represents a vertical central sectionalelevation of the part-s of a pump in which my improvements are made.Fig. 2 represents the ring h, cross-bar o, and bolt and nut connectingthesame. Fig. 3 is a plan view of o of Figs. l and 2.

Like letters refer to like parts.

In the drawings, A represents a pump-barrel provided with an interioriiange, b, at asufiicient distance from the lower end thereof to permitdriving the end ofthe stock C securely into its place without disturbingthe flange b or its attached parts, preferably leaving some free space,as shown. Above the flange I), and within the barrel A,is placed acylinder, D, of glass, hard rubber, porcelain, metal, or enameled metal,provided with a dange, c, which rests upon a packing-ring, f,which bearsupon the angeb. Upon the angecis placed apaekingrin g, g. Through thecylinder D is passed a metallic ring, h, provided with arms t', leavingWater-Ways between them. Attached to the arms i is a bolt or stem, j.Said ringhhas an exterior iiange, 7c, which rests upon the packingringg, placed upon the fiange c. The cylinder D is free from the barrelA andthe ring h from the flange b, a sufiicient space being left to permitthe barrel A to shrink without coming into lateral contact with themetallic parts. To prevent the water from ruiming back through the saidfree space around the cylinder. D and the ring h is the office of thepacking-ringf. Likewisethe packing-ring g prevents the escape of waterbetween the fianges lc and e. The bolt or stem 7' passes through anopening in the cross-bar o,is threaded, and provided with the nut t.

Vhen all the parts mentioned are placed in their several positions, thecylinder is rm- 1y clamped to the fiange b by tightening the nut tagainst the cross-bars 0, which bears against the under side of thefiange b,- and it is obvious that said parts may be taken out of thepump-barrel for repair or renewal at any time by removing the nut t.

It will be observed that the ring 71 with its flange k, stem j, and nutt, together with the cross-bar o, form a mechanism by which thecylinder` D is secured to the p ump-barrel A by vertical longitudinalpressure on the fiange b, which forms an integral part of the pumpbarrelA.

It will also be observed that the pressure on the flange b is againstthe ends of the grain or fibers of the wood in the only direction inAwhich the wood will not shrink or swell, and also that there is nolateral Contact between the wood and inet-allie parts. rlhe upper edgeor face Z of the ring h forms a valve-seat for the check-valve m.

The distinguishing feature of .my invention is an internal fiange withinthe ends of the pump-barrel, having shoulders upon both its upper andunder sides, to which an internal cylinder may be attached, pointing ineither direction.

I am aware that pumps with internal shoulders have heretofore been madeon which internal cylinders with flanges have been placed; but I do notclaim such constructions.

What I claim isl. A pump barrel provided between the ends of its borewith an internal flange, in combination with an internal cylinderattached to said iiange at one of its ends, substantially as specified.

2. A pump-barrel provided with internal fiange within the ends of' itsbore, in combination with an internal fianged cylinder and a check-valveseat, all within each other, and mechanism to unite saidparts,substantially as specified.

8. In combination with a pump-barrel having internal fiange between theends of its bore and an internally-fianged internal cylinder, a flangedring, all within each other, and mechanism to unite said parts, allbeing free from lateral contact, substantially as specified.

4C.A In combination with an internally-flanged pump-barrel andinternally-hanged cylinder, a fianged ring provided with water-ways,arms, and astem, and mechanism to unite said parts, substantially asspecified.

5. The combination, with a pump -barrel provided with an internal flangebetween the ends of its bore and internal flanged cylinder and flangedring attached thereto, ofthe packing between said flanges, substantiallyas specified.

6. In combination with a pump-barrel, A, provided with an internalflange, b, a cylinder, D, provided with flange c, and a ring, h, havingvalve-seat and flange k, arms z', stem j, cross-bar o, and nut t,substantially as specified.

7. AA pump-barrel, A, provided with fiange b, and cylinder D, withflange e, in combination with ring 7L, with valve-seat l, and flange k,having arms fi, stem j, cross-bar o, nut t, valve m, and packing f andg, substantially as specified.

8. A pump-barrel provided with internal flange within the ends of itsbore, in combination with a flanged cylinder and mechanism for unitingsaid flanges, substantially as specified. A
